Oh gosh!
don't listen to that nurse again!
Your son is dehydrated... how can he go 1 week without drinking milk... much less no liquids for a whole day! WHY?
WHY must you take away his bottle NOW!
Is there a reason? This is a kind of "weaning"...whether by bottle or boob. It has to do with their nutrition and intake too....and their health, as you saw.
MANY babies/toddlers will NOT immediately take milk from a cup...it is a process. So what. MANY kids in ALL the different countries in the world use different "rules." In some cultures, a child uses a bottle even though they are older. To me, the main thing is that they are getting their proper intake, their nutrition, NOT being put in harms' way with their health.... and the emotional/developmental level of the child.
Please, you can't just starve him of his nutritional requirements or put him in danger of dehydration.... JUST for the sake of getting rid of his milk bottle. Dehydration is very serious... also, they need "whole" milk as the milk fats in it is an important nutrient for proper brain growth.
MANY MANY toddlers, STILL drink MILK from a bottle... in your case, I wouldn't force it.
Take care,
Susan
